A CCNA1 Missense Variant Associated With Chromatid Non-Disjunction in Abnormal-Headed Sperm and Male Infertility.
This study establishes the first clinical association between CCNA1 mutations and chromatid non-disjunction in human spermatogenesis, highlighting the limitations of current morphology-based diagnostic thresholds and supports cytogenetic and genomic assessment for severe teratozoospermia (especially head abnormalities)...
